There are differences in installation of Solaris 2.5 software on a networked x86 system:
kdmconfig is called by sysidconfig and replaces devconfig during installation.
When bootparams database server is queried, if the ethernet and hosts maps are set correctly, installation proceeds without questions. If there are discrepancies, or the system is stand-alone, a series of screens appear asking you to define the keyboard, mouse, and display attached to the system. See kdmconfig(1M).
There are differences in formatting SCSI and IDE disks for x86 systems.
The format(1M) utility is now available to format, label, analyze, and repair SCSI disks. This utility is included with the addbadsec(1M), diskscan(1M), fdisk(1M), and fmthard(1M) commands available in the Solaris 2.1 for x86 release. To format IDE disks use the DOS format utility; however to label, analyze and repair IDE disks on x86 systems use the Solaris format(1M) utility.
There is a change in the support for parallel PostScriptTM printers on x86 systems:
The lp driver has been modified, so that setup for a parallel PostScript printer in x86 systems is now identical to the setup of a serial printer. The only difference is when you need to specify the device name of the port.
The following files are no longer part of Solaris 2.5:
/etc/lp/fd/ppostio.fd
/etc/lp/fd/ppostior.fd
/usr/share/lib/terminfo/P/PPS
/usr/share/lib/terminfo/P/PPSR
The x86 lp driver now takes advantage of added ioctls in postio.
